The LBTEK aspheric lens five-axis fiber coupler/collimator with a focal length of 11 mm offers three coating options (A/B/C), covering wavelengths from 350-1700 nm. While the connector and fiber remain stationary, the built-in lens provides five degrees of freedom for alignment: linear alignment in X and Y directions, pitch and yaw angular alignment, and Z-axis adjustment using combined pitch and yaw movements. The aspheric lens has a travel range of ±0.7 mm in X and Y directions with a resolution of 317 µm per revolution. The Z-direction travel range is ±1.0 mm with a resolution of 200 µm per revolution. Additionally, loosening the three flat-head screws on the front panel allows rotation of the connector for polarization-maintaining fiber alignment. After alignment is completed, tighten the locking screws on the side of the housing to secure the X and Y positions. The lock ring on the Zθ adjuster can fix the pitch/yaw position.
